He graduates from the cadet's school in 1836 having studied Czech language and moved back to Vienna with his regiment.

He is reassigned to the Hungarian regiment Bakonyi number 33 based in Milan under Austrian rule at the time.

In 1867, in his letter to the Eichstätt Beekeepers News, he mentions that: Within the last twelve years only once we had a season like this..." indicating he may have started as early as 1856.

In 1870, advertisements for his queens are described as "beautiful and mild mannered bees, guaranteed by a 12 years long selection process."

The house had a big garden in front of it with the northern side ending with the banks of the Brenta river lined with hedges.

The garden was filled with vine, fruit trees, roses and other flowers and a section was dedicated to growing vegetables.

[1] Franz seem to have enjoyed his life in Dolo and he had extensive contacts with other beekeepers due to his fame as the inventor of the extractor in 1865.

He also visited several other exhibits in Verona and did presented at the Comizio Agrario di Dolo that same year where he offered to help with public beekeeping courses.

The house was sold at auction, and he moved to a rented place in the Palazzo Rizzi with his wife, selling everything.

On July 1, 1865, in an article in Eichstraett Beekeeping News, he explains his old crushing method of cutting the cells from the honeycomb base.

[3] His original idea was simply to support combs in a metal framework and then spin them around within a container to collect honey as it was thrown out by centrifugal force.

This meant that honeycombs could be returned to a hive empty but undamaged, saving the bees a vast amount of time and energy rebuilding the wax.

A frame of honey was put in a dish in a basket and his son started playing with it by whirling it by the rope attached to the handle.

In his article published July 1, 1865, he mentions his knowledge of centrifuging machines used in sugar refineries at the time and it is not impossible the jump to the honey extractor took place then.

because of the length of the beam, the speed of extraction was significantly faster but the size of the machine made its operation cumbersome.

According to Charles Dadant, they were entered by his foreman Angelo Lessame of Dolo, province of Venice.

[5][2] The idea of the extractor was published in several beekeeping newspapers and several versions were manufactured and sold based on his invention.
